Multifocal electroretinogram in clinically significant diabetic macular edema.
OBJECTIVE To explore the multifocal electroretinogram in patients with nonproliferative diabetic retinopathy with clinically-significant macular edema. METHODS Forty-one eyes with clinically significant macular edema were tested. The latencies and amplitudes of average responses of 5 eccentric rings from 0 to 26 degrees relative to the fixation point were compared with normal values obtained ...
متن کاملMultifocal electroretinogram in myopia.
PURPOSE To investigate early changes of retinal function in myopic eyes, patients with various degrees of myopia underwent multifocal electroretinography (multifocal ERG). METHODS Thirty young patients (mean age, 26.1 years) were divided into three groups according to the degree of refractive error: emmetropia/low, medium, and high myopia. All groups were matched by sex and age. All subjects ...
متن کاملMultifocal electroretinogram delays predict sites of subsequent diabetic retinopathy.
PURPOSE To examine the potential of abnormal mfERGs to predict the development of diabetic retinopathy at corresponding retinal locations 1 year later. METHODS One eye of 11 diabetic patients with nonproliferative diabetic retinopathy (NPDR) and 11 diabetic patients without retinopathy were retested 12 months after initial testing. At each time, mfERGs were recorded from 103 retinal locations...
متن کاملMultifocal electroretinogram in birdshot chorioretinopathy.
PURPOSE To characterize multifocal electroretinogram parameters in patients with birdshot chorioretinopathy. METHODS Twenty-eight patients with birdshot chorioretinopathy consecutively included from 2006 to 2011 were matched to 27 healthy subjects for age, axial length, and lens status. Multifocal electroretinogram was prospectively evaluated using the Vision Monitor system. RESULTS Birdsho...
متن کاملClinical evaluation of multifocal electroretinogram.
PURPOSE To compare the multifocal electroretinogram (ERG) system to conventional ganzfeld and focal ERGs obtained from patients with known retinal diseases to assess its clinical applicability. METHODS A multi-input system analysis was used to explore the field topography of ERG responses to local luminance modulation in patients with retinitis pigmentosa, pericentral pigmentary retinal dystr...
